- Patented June 1940 UNITED Vsfrii'rflss [monies PATENT- oFFICE Heretofore, it has been the practice to lill K Lscupper holes oivessels carrying oil with wooden plugs andthis invention has for its object to provide an improved plug for this purpose.

A In accomplishing thiscbject, I have provided the improved details of construction lthe preferred formk of which isillustrated in the accompanying drawing, .wherein- Figure 1 is a plan view of the plug device. Figure 2 is an end view-thereof.

` Figure 3 is a plan view of a fragment of `a lship owing a scupper hole and plug clamping means.

rods may rest therein when not in use.

Figure 4 is a view vin side elevation of the structure of Figure 3. Figure 5 is a view along section 5- 5 lof Fig*- ure 3.

The plug device consists of a plug element or body l anda face plate I. The plug body is made up of a metallic core, preferably-ofV steel about 1A thick and a covering of lead. They lead is cast on the core completely covering the same, thereby giving the core added strength.

The layer of lead should be about 1/2 kinch thick;v

The plug body is tapered in the manner shown in n Figures 1 and 2 to facilitate inserting it in place.

'Ihe face plate is attached'to the broader or rear end of the plug and extends about equalv distances on each side thereof. A notch or recess 3 is formed in the plate at each side of the plug for convenient engagement with clamps so that it maybe conveniently clamped in the scupper hole. The face plate is further` providedv y I .by the plug may be securely held in the scupper with a ring 2 whereby a chain may be attached to the plug, the other end of the chain may be "as ati-.ached to the shackle s, Figure 4.

Clamping means, 4;' 4",l illustrated in rFigures 3, 4 and 5 may be provided and in suchA case they 1 should Vbe attached to the side of the' vessel adi jacent thel scupper hole l vwhich itis desiredto close. The clamping means include rods 4, pref- 5 erablymade of brass, pivotally attached to the vessel, one at each yside of the hole vand clamp units 4'; one on each rod. Nuts are threaded on the rodsto draw the clamp units 4 into the notches in the face plate and thereby draw the l0 i plug into the hole. Support elements` are positioned adjacent the pivots of rods 4 so that, the

Having described the invention, what I claimA to be' new is: 15

y 1. A plug device for closinga scupper hole l aboa'rdship comprising a plug body'of a size to lclose the hole, said body includingk a metallic core and a unitary lead casing` integrally at tached thereto and completely covering the same, 20` a plate member secured at itsmid-portion toone end of said body and extending beyond oppositer sides'thereof to provide arms, eachc which are provided with a recess to receive clamping means whereby thelplug may be held in thev hole. v25

2.. A scupper plug as claimed in claim l wherer inthe plug .body is. tapered from the larger enclv at the plate membereto `the front end.

' 3. -A scupper plug as' claimed in claim l and including clamping -means `adapted to be secured 30v to the side of the ship and cocperate'with said recesses in the arms 'in' the plate member *Wheree hole. v
